Magnetic 'T-Budbots' Made from Tea Plants Kill and Clean Biofilm

Biofilms -- microbial communities that form slimy layers on surfaces -- are difficult to treat and remove, often because the microbes release molecules that block the entry of antibiotics and other ...

Switching Up: Marine Bacteria Shift Between Lifestyles to Get the Best Resources

Researchers have found that marine bacteria exploit resource patches efficiently by switching between attached and planktonic lifestyles, and ...

Genome of Alexander Fleming's Original Penicillin-Producing Mold Sequenced

Researchers have sequenced the genome of Alexander Fleming's penicillin mould for the first time and compared it to later ...

Customizable Synthetic Antibiotic Outmaneuvers Resistant Bacteria

Antibiotic resistance is one of the world's most urgent public health threats. In the United States alone, tens of thousands of deaths result each year from drug-resistant strains of common bacteria ...

Looking at Evolution's Genealogy from Home

Evolution leaves its traces -- in particular -- in genomes. Researchers used '2-n-way' software to determine the relationships between species or individuals and compare any genome of and ...

A New Strategy of Cell Entry for Some Types of Parvoviruses

Researchers have uncovered a new parvovirus strategy for reaching the cell nucleus which is their site of replication. This new method of entry is a good example of host-driven ...

Technique Permits Convenient, Precise Optical Imaging of Individual Proteins

In a new study, researchers describe a method for examining proteins in keen detail. To do this, his group makes clever use of a phenomenon known as surface plasmon resonance (SPR), incorporating it ...

Mosquito-Borne Viruses Linked to Stroke

A deadly combination of two mosquito-borne viruses may be a trigger for stroke, new research has ...

New High-Speed Test Shows How Antibiotics Combine to Kill Bacteria

Researchers have developed a new method to determine - rapidly, easily and cheaply - how effective two antibiotics combined can be in stopping bacterial growth. The new method is simple for ...

Engineered Bacteria Churn out Cancer Biomarkers

Pity the glycan. A lab has created these very tools by commandeering simple, single-celled microorganisms - namely E. coli bacteria - and engineering them to explore the complex process of ...

Scientists Uncover the Structural Mechanism of Coronavirus Receptor Binding

The spike protein on the surface of the SARS-CoV-2 coronavirus can adopt at least ten distinct structural states, when in contact with the human virus receptor ACE2, according to new ...

Discovery of Microbes With Mixed Membranes Sheds New Light on Early Evolution of Life

Current research suggests that more complex life-forms, including humans, evolved from a symbiosis event between bacteria and another single-celled organism known as archaea. However, evidence of a ...

Social Distancing and Microbial Health

Social distancing is a key component of the expert-recommended strategy to reduce the spread of COVID-19. Avoiding contact with others, however, may have repercussions in a person's gut ...

Scientists Explaining How Diverse Species Coexist in Microbial Communities

Researchers use mathematical modeling to explore how species diversity in a bacterial community is affected when the nutrients the microbes depend upon are only seasonally ...

Epidemics and Pandemics Can Exacerbate Xenophobia, Bigotry

Instincts developed to protect us from illnesses can generalize into avoidance of healthy individuals who simply look, speak or live ...

Key Role of Immune Cells in Brain Infection

Researchers have identified the specific type of immune cell that induces brain inflammation in herpes simplex virus (HSV) encephalitis. Crucially, they have also determined the signalling protein ...

Tiny Protein Motor Fuels Bacterial Movement

The ability to move is key for bacteria like some strains of salmonella and E. coli to efficiently spread infections. They can propel themselves forward using threads, known as flagella, powered by ...

Rising Temperatures Could Shift US West Nile Virus Transmission

West Nile virus spreads most efficiently in the US at temperatures between 24-25 degrees Celsius (75.2-77 degrees Fahrenheit), a new study ...

Ocean Algae Get 'Coup De Grace' from Viruses

Scientists have long believed that ocean viruses always quickly kill algae, but new research shows they live in harmony with algae and viruses provide a 'coup de grace' only when blooms of ...

Small 'Cain-and-Abel' Molecule Discovered

A new bacterial molecule with the unsavory tendency to track down and kill others of its own kind has been discovered in the human microbiome. Named Streptosactin, it is the first small molecule ...

Animals' Magnetic 'Sixth' Sense May Come from Bacteria

A researcher may help answer why some animals have a magnetic 'sixth' sense, such as sea turtles' ability to return to the beach where they were born. The researchers proposes that the ...

Tiny Antibody Component Highly Effective Against SARS-COV-2 in Animal Studies

Scientists have isolated the smallest biological molecule to date that completely and specifically neutralizes the SARS-CoV-2 virus, which is the cause of COVID-19. This antibody component, which is ...

When Methane-Eating Microbes Eat Ammonia Instead

As a side effect of their metabolism, microorganisms living on methane can also convert ammonia. In the process, they produce nitric oxide (NO), a central molecule in the global nitrogen cycle. ...

Uncovering the Science of Indigenous Fermentation

Wine scientists are shedding scientific light on the processes underlying traditional practices of Australian Aboriginal people to produce fermented beverages. The scientists have discovered the ...
